To all whom it may cir/neem Be it known that I, Hnnnnn'r CHARLES NEVILLE, a citizen vot the lllnitcd'States, ren siding at lvutcrloo, in the county of Bleekhawk andt-u'te oi; Iowa, here invented o certain new and-useful Improvementin Cltches, of which the following is :i spccii This invention relates to clutches, und the prinmry object thereof is to provide n clutch which Will not slip.

Another object to so construct :i clutch of this character in which n friction clutch is used to start the cor or other object- Ito he driven and n solid or positive drive from the motor to the r for heels provided With the foregoing und other ohjecte in view, which will appear ne the description proceeds;7 the invention rcs les in the com bination and arrangement of parte sind in the details of construction liercinifter dcscribed and claimed` it being undeiwltotr-d that changes in the precise embodiment op? the invention herein disclosed may be mede Within the Scope of what is claimed Without de drting from the spirit of the! invention.

This shaft 1 has a longitudinolbY extendingl` slot therein,

through which extends :i pin i projecting et its opposite ends above md below said shaft.'

carries at provided so j for a coiled clutch spring 21, 'the other end of which is mounted in the sleeve formed by the flange 8 of collar 6 as is shown clearly in Fig. 1.

The tivo nuts 17 are designed to maintain` the adjustment of sleeve 14 relatively to sleeve 12, while those 18 and 19 are designed for increasing or reducing the tension of the clutch spring 21.

The sleeve 14 has a radially extending flange 14 at its front end, and to this flange is designed to bebolted a :friction clutch,

which may be of any desired construction,

being preferably in the form of a leather- .threaded engagement With the collar 23 on the periphery thereof, and is provided at its other end with an inturned flange 29.

The pin 5 is similarly held in position by the thrust race 9 which prevents said pin from slipping transversely through the shaft.

A heavy coiled spring 3() encircles the rear end of shaft 1, engaging at its front end with the rear end of sleeve 12, and at its rear end the collar 6, and exerts its tension to retain the clutch members 10 and 13 tightly in operativeengagement.

A pair-of -clutch levers 31 mounted on a shaft 32 are positioned for coperation with the thrust ball race 24, and when depressed by the driver will operate to move the ball race 24 forward, carrying with it the collar 23 and the dog clutch member 13. lVhen the teeth of the tivo dog clutches 10 and 13 are disengaged, the tivo adjusting ring nuts 17 are engaged by the collar 23 and are carried back with said collar, thereby releasing the cone clutch from the fiy Wheel. Obviously, when the clutch is let in the reverse action `will occur; and said ,cone clutch will first take the drive and after the collar leaves the nuts 1.7, the positive clutches 10 and 13 will come into engagement. The tension on the `clutch proper is not necessarily as tight as the conventional form v of clutch,A and in fact need be only a trifle tighter than a sl ipping contact, since the positive clutches 10 and Y13 perform all the hard Work.

From the above description it will be obvious that the eene clutch carried by the {iange 14 will be used to sta-rt the car and the driving thereof will be accomplished.

by the clutches 10 and 13 giving a solid drive from the motor tothe rear wheels,

and preventing all possibilitylof Ithe slipping of the clutch.

The foregoing description and the drawings have reference to' what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction.

and arrangement and eombinationof parts, materials, dimensions, etc., a's vmay prove expedient and fall Within the scopevof the claimed invention.

`Having thus fully described my invention, What/1 claim as new and desire to secure by Letters Patent, is:

1. In a clutch of the class described, the combination of a shaft having a longitudinally disposed slot extending therethrough, a pin mounted to reciprocate in said slot andprojecting at its ends beyond said shaft, another pin extending transversely through said'shaft at a point spaced from said first-mentioned pin, a thrust collar secured by said second-mentioned pin and having a flange concentric with said shaft to'form a spring housing, a. ball race at the rear of said collar to receive the /thrust therefrom and to hold said pin in position, a sleeve keyed to slide on said shaft, a clutch member fixed to said sleeve, a fly Wheel rotatably supporting said shaft and having friction and positive clutch members, the latter to coperate With said sleeve carried clutch member and form a positive connection between said wheel and shaft, another sleeve slidable on said shaft engaging sleeve With a slot registering With the shaft slot through which and said firstmentioned sleeve said first mentioned pin extends, a friction clutch member carried by the outer sleeve adapted to coperate with the friction clutch member on the fly wheel, springs engaging said sleeves and thrust collar to hold the clutches engaged, and n'igans for releasing first the positive clutch and then the friction clutch.
